After thumbnailing, it’s often time for more reference. Folks around me have commented on how PB resembles me in real life. Actually, all our characters do, because I’m mugging in front of a mirror in order to get those expressions and hands the way I want them. Or forcing my wife or son to take pictures of me in ridiculous poses to work from. Clothed, of course (you perv). Drapery– the way clothing folds and hangs around the body is something that reference can really help out with.
